Is DMD p.Lys2785= (c.8355G>A) pathogenic?

DMD p.Lys2785= (c.8355G>A) is classified Likely benign in DMD (ClinVar, Single submitter, 2 submitters; last evaluated 2023-02-21). Very rare (popmax 0.00217%, amr); Associated with Duchenne muscular dystrophy.

What condition is associated with DMD p.Lys2785= (c.8355G>A)?

DMD p.Lys2785= (c.8355G>A) is associated with Duchenne muscular dystrophy, cardiomyopathy, Becker muscular dystrophy (ClinVar).

How common is DMD p.Lys2785= (c.8355G>A) in the general population?

DMD p.Lys2785= (c.8355G>A) is very rare (popmax 0.00217%, amr) (gnomAD).

How is Duchenne muscular dystrophy inherited?

Typically X-linked recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
